DNS Checker: Ping & Lookup

On-device DNS diagnostics—nothing stored, synced, or sent except to the resolver you query. No accounts, ads, or analytics. Look up A/AAAA/CNAME/MX/TXT, reverse IPs to hostnames, tap-to-copy, paste from clipboard, and keep results for this session only. In-app Help and tooltips explain every screen. Share via the system sheet when you choose. Pro (one-time): all record types, multi-record, custom DNS, dig-style output, DNSSEC, propagation across public resolvers, batch + CSV export, and Share Sheet Check DNS. Clear session or quit—everything’s gone.
